So the roads where I am at are full of rocks etc and they have been murder on my Big Bens. I have been running tire liners which have been great on extending their use and preventing weekly flats. So I am in the market for some new tires and I want to know if anyone has tried anything else? I still want to stick with the 2.15 size or close too and I want the sleek profile as well as I have a platinum and speed is important to me. I am also about 2000 miles on my chain and I am looking to replace it as well. What is the best chain I can put on this bike. I am okay replacing it with what came on it but if I can upgrade into a better chain then I want to do so.
